I think you are actually facing the most obvious problem of the whole idea here: By rendering into a texture you put load on the CPU for doing a job that could be much better done by appropriate OpenGL hardware. You could try to circumvent this problem by shifting the render-to-texture job onto the graphics board, but such a solution would come out to be _very_ hardware-specific, i.e.totally non-portable. If you have a 'spare' CPU you could try to run the job there, although synchronization might be tricky, Martin. -- Unix _IS_ user friendly - it's just selective about who its friends are ! -------------------------------------------------------------------------- ------------------------------------------------------- This SF.net email is sponsored by: Splunk Inc.
